I have become quite frustrated as the server no longer runs more than 2 days without a hard lockup. I have run memtest over night with no errors. I have followed the guidance for Ryzen power states and RAM. The server had previously been running quite stably for a few years with the current hardware. When I checked the video output at the most recent crash, the display is attached. I can not pinpoint any specific activity prior to the crash and the system log has no errors leading up to the crash.

Any help would be greatly appreciated!

I dont see anything obvious logged other than your jetkvm device seems to have the usb connection reset. Do you recall messing with your JetKVM device? Enabling/disabling options that would essentially cause the USB connection to reset?

I suggest running unraid in safe boot mode and keeping containers/VMs disabled for a few days to ensure it's not being caused by a rogue plugin or container/VM.

If it can stay running as a basic NAS start enabling services 1 at a time, containers as well.
